Linux Mount Storage Method

Application of virtual machine due to total downtime, after processing the allocation of more than my 100G space, or hard to pay attention to the well, Mount method is as follows:

Initial disk mount Condition:
[Email protected] ~]# df-h
Filesystem Size used Avail use% mounted on
/dev/sda2 19G 9.0G 9.1G 50%/
/DEV/SDA4 44G 181M 41G 1%/u01
/DEV/SDA1 99M 22M 73M 23%/boot
Tmpfs 4.0G 0 4.0G 0%/dev/shm

To partition a disk with Fdisk:
[Email protected] ~]# Fdisk/dev/sdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF Disklabel
Building a new DOS disklabel. Changes'll remain in memory only,
Until decide to write them. After that, of course, the previous
Content won ' t be recoverable.

The number of cylinders for this disk was set to 13054.
There is nothing wrong with the, but this is larger than 1024,
And could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from the other OSs
(e.g., DOS fdisk, OS/2 fdisk)
